Ultrastructural observations suggesting merocrine secretion in the initial segment of the mammalian epididymis
Cell and Tissue Research
|November 23, 1977
Principal cells in the initial segment of the epididymis in horses, cattle, pigs, sheep, dogs, cats, and rabbits have an abundant, partly rough, endoplasmic reticulum and a large Golgi complex. Small vacuoles with opaque content seem to be formed by the Golgi complex and move to the cell apex, where they empty their contents into the lumen by a merocrine mechanism.
